ROBERT G. WEISSEL, OF OAKLAND, CALIFORNIA.

LEVER-LOOK.

Specification of Letters Patent.

Patented A11 '7, 1917.

Application filed May 29, 1917. Serial No. 171,643.

To all whom it may concern:

Be it known that 1, ROBERT G. WEISSEL, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented certain new and useful Improvements in Lever- Locks, ofwhich the following is a specification- The present invention relates toa lock device for levers and more particularly to a device for looking amotor vehicle gear shift lever from movement by unauthorized personswhen it is desired to leave a motor vehicle unattended.

The invention consists broadly in providing a lock structure capable ofattachment to any well known type of gear shift lever, and designed whenin operative position to have engagement with a stationary portion ofthe vehicle, preferably the lever guide, to lock the lever fromoperative movement, and preferably in what is commonly termed reversedposition.

The invention comprises a casing within which is mounted a locking boltand which is connected through a pivotal link with a latch membercapable of operation to actuate the locking bolt, and when in oneposition capable of movement for reception into a key controlled lockingmechanism.

With the above mentioned and other objects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings and pointed out inthe claims hereto appended; it being understood that various changes inthe form, proportion, size and minor details of construction within thescope of the claims may be resorted to without departing from the spiritor sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to theaccompanying drawings, wherein Figure 1 is a view in side elevatlon ofthe preferred embodiment of my invention, applied to a gear shift lever.

Fig. 2 is a view in end elevation.

Fig. 3 is a view in top plan.

Fig. 4 is a vertical sectional View taken centrally through the lockmechanism thereof with the mechanism in unlocked position.

Referring more particularly to the several views of the drawings,wherein like characters of reference designate corresponding parts, 1indicates a suitable gear shift lever of the well known type, and thesame projects through a housing 2, preferably formed with the usualH-slot guide 3 in which the lever moves; the slot controlling theoperative movement of the lever. In the drawing the lever is illustratedin operative position, and in which position the shiftable gears,controlled thereby, are preferably in engaged relation to cause therearward or reverse movement of the vehicle.

Secured to and movable with the lever at one side thereof, immediatelyabove the upper surface of the housing 2, is my improved lock mechanism,consisting of the side plates 4 which are held in parallel spacedrelation in any suitable manner; said side plates bein permanentlysecured to the lever by a suita 1e attaching means 5, preferably in theform of a rivet. Positioned between the plates 4 and adapted to havevertical lineal movement is a locking bolt 6 having an offset lower end7 and provided with an elongated guide opening 8 through which passes apin 9 supported by the plates 4, and providing a guide for the bolt. Theoffset portion of the locking bolt is adapted, when the same is movedinto operative position, as'in Fig. 1, to be received in an opening 10,formed in the upper surface of the housing 2 at one side and adjacentthe rear edge of the reverse slot opening in said cover or housing. Theupper end of said lock bolt is pivotally connected, as at 11, to one endof a link 12, fulcrumed as at 13, and pivotally carrying, as at 14, atits opposite end an operating member 15 formed with an L-head 16providing a latch which is formed in its outer face with a notch 17- Themember 15 is adapted to be manually swung outwardly and upwardly on itspivotal point 14 from the unlocked position, as illustrated in Fig. 4,and thence moved lineally and inwardly to a position as in Fig.

1, which movement oscillates the link 12 on its fulcrum 13 which causesa separation of the pivoted ends of the keeper member and bolt and alineal movement of the locking bolt 6 downwardly to the position as inFig- 1 of the drawings, at which time the offset end 7 thereof isreceived in the opening 10 to lock the lever from movement. when in thislocking position the head 16 of the latch member is adapted to be forcedinwardly to enable the notch 17 thereof to be engaged by a suitable pawl18 within the key controlled lock mechanism 19, at which time the leveris locked from operative movement.

Between the plates 4 are mounted the springs 20 and 21, the spring 20being coiled about the rivet 5 and provided at its outer free end with araised portion 22. which is adapted to be received in the notch 17 andretain the operating member 15 in its retracted position and to preventthe same from rattling, and the free rear end of said spring bearsupwardly on the locking bolt 6 to normally maintain the same in itsraised or unlocked position. The spring 21 is also coiled about thelower rivet 5 and the free end thereof normally abuts against the rearface of the operating member- 15 to assist in removing the same frombetween the plates when the outer free end of the spring 20 is manuallydepressed to withdraw, the portion 22 thereof from the notch 17 In orderto throw the member 15 from the locking mechanism 19 on the operation ofthe barrel 23 thereof, a spring 24 is employed' It will be apparent thatI have provided a construction composed of very few elements and it iscapable of attachment to a lever at very little expense; one which iscapable of operation to throw the locking bolt thereof into eitheroperative or in-' operative position, and one wherein the operatingmeans also serves as a latch for engaging the locking member. While Ihave illustrated my look as applied to a lever operating through a guideof the H-type, it is apparent that the same may be applied equally aswell to a construction of the ball and socket type.

By pivotally connecting one end of the locking bolt and keeper member tothe opposite ends of a fulcrum link, the oscillation of the link, due tomanual movement of the latch, causes a separation of the pivoted ends ofsaid members, and by positioning the key controlled locking mechanism adistance from the fulcrum point of the connecting link, a slightoscillation of the link is required, when the bolt is in unlockedposition, to enable the latch member to be received within the lockinmechanism, which movement causes a lineal move ment of the locking boltto project the free end thereof into the opening in the guide p at aHaving thus described my invention, what I claim as new and desire toprotect by Letters Patent is 1. In combination with a movable member, astationary member associated therewith and provided with a locking boltreceiving opening, a lockingmechanism carried by the movable. member tolock the same to the stationary member and comprising a fulcrurn'edlink, lineally movable locking bolt pivotally connected to one endthereof for the reception of its free end within said opening, anoperating latch member pivotally connected at one end to movement ofsaid locking bolt for reception within said opening.-

2. In combination with a movable lever, a stationary member throughwhich the lever extends and relatively to which the same operates,mechanism carried by the lever above said stationary member for lockingsaid lever thereto and comprising a fulcrumed link,- a lineally movablelocking bolt fulcrumed at one end to said link and movable lineally tothe lever for engaging said stationary member, a manually movable latchpivotally connected at one end to said link and adapted for swingingmovement on its fulcrum, and locking devices for receiving said latch onthe movement of said bolt into locked engagement with said stationarymember,

8. In combination with a lever, a stationary member through which thesame extends and relatively to which the same 0perates, a lever lockcarried by the lever above said stationary member and comprising afulcrum link, a lineally movable locking bolt pivotally connected at oneend to one end of said link, a locking mechanism above said link, alatch member pivotally connected at one end to the opposite end of saidlink and forv engagement at its free end with said locking mechanism,the movement of said latch into engagement with said locking mechanismcausing a movement of said locking bolt into locked engagement with saidstationary member.
